WON'T START

1991 Mercury Capri • 6 cylinder 2WD Manual • 160,000 miles

Car has 160000 miles, timing belt was replaced @ 110000 miles, replaced cap & rotor plugs & wires shotly after I bought it @ 147000 miles, I was driving home on the highway 65mph and the tach jumped from 2700 rpm to 3200 rpm for an instant then ran fine then about 1/2 mile down the road the car shut off. Got the car home, it started for about 30 seconds then would not start. The next day it started for about 2 minutes then stalled. I thought it was the fuel pump, replaced it and the filter mounted on the firewall. I checked to see if I was getting fuel it and it is. Still the car will not start. Could this be electrical or something else common for these cars?
